Specification of Letters Patent.

Patented Mar. 28, 1916.

Original application filed Januaryr 9, 1915, Serial No. 1,306. .Dividedand this application filed October 13,

To all 'whom it may concern Be it known that I, FRANK E. BOWERS., acitizen of the United States, residing at Indianapolis, in the county ofMarion and StateV of Indiana, have invented a new and useful Incubator,of which the following is a specification.

My invention relates toincubators in which there is a movable hot waterheating element, and its object is to provide for a more uniform heatingfrom this heating ele-- ment. Y

rlhis application is a division of my copending application Ser. No.1306, filed J an. 9,1915.

The accompanying drawing illustrates my invention.

Figure 1 is aperspective view of an incubator embodying my invention;Fig. 2 is a horizontal sectional view through the heating element,showing the parts at the vent opening partly in planand partly insection on a different plane from the remainder of the figure; and Fig.3 is a section on the line 3 3 of Fig. 2.

The incubator shown comprises a base 10 for supporting the egg tray 11,and a removable cover 12 which .rests on 'the base 10 and covers the eggtray. This cover is conveniently made of metal with a suitable heatinsulating lining, the details of which are immaterial here.

Suitably mounted in the removable cover 12 is a hollow metal frame 15,which is shown in the form of a hollow square, from which frame 15 twopipes 16 and 17 extend at higher and lower levels to a heat-receivingcasing 1S, which is supported by the pipes 16 and 17 and fits over asuitable heat-producing device, such` as a lamp 19 resting on an ,arm 2Oextending from the base 10. The casing 18 is conveniently provided witha filling cap 21, for filling such casing and the interconnected pipes16 and 17 and the frame 15 with water. These parts are not completelyfilled, so as to allow room for expansion of the water on heating. Onheating the water circulates by gravity from the heat-receiving casinglSthrough the pipe 16, around and through the frame 15, and back throughthe pipe 17 to the heatreceiving casing 18, and the heat is radiatedfrom the frame 15 downward to the eggs in Serial No. 55,596.

the tray 11. The heating effect may be regulated in any suitable manner,as by an automatic regulator 22 of any desired construction.

F or the more uniform distribution of the heat from the frame 15, thepipe 16 discharges into such frame by way of a trough V25 which islocated in the receiving side of the square frame 15, this trough beingboth of less width and less height than the side of the frame in whichit is located and being open at the top and preferably very slightlyspaced from the frame at the bottom. The water which is discharged intothe trough from the pipe 16 in the main travels the length of the troughbefore striking the` walls of the frame 15, and the discharge end of thetrough is provided with a curved baffle plate 26 for guiding the wateraround the cornerof the frame 15 with a minimum. of eddying. be providedat the next corner of the frame, for similarly guiding the water. Thepockets 28 and 29 which are-formed between the trough 25 and the wallsof the frame 15 contain comparatively still water, which serves totemper the heat which is radiated from that side of the frame 15 towhich thel hot water from the casing 1S is supplied, these two pocketsbeing interconnected by the narrow space beneath the trough. r1`hisheating unit, comprising the partsl, 16, 17, and 18, is provided with avent opening of special form, terminating in the pipe 33. This forms nopart of the present invention, but is the subject-matter of my aforesaidco-pending application of which the present application is a division.

I claim as my invention:V

1. A heating unit for incubators, comprising a hollow, water-containing,radiating frame, a heat-receiving casing, pipes connecting said frameand casingV on differentlevels for providing a water circulation, and atrough located in Said frame in position to receive the water dischargedthere.- into from one of said pipes, said trough extending along saidframe and being spaced from the walls thereof at the top, the bottom,and the sides. Y

2. A heating unit for incubators, comprisingV a hollow,water-containing, kradiating frame, a heat-receiving casing, pipes Asimilar baiiie plate 27 may a los connecting said frame and casing ondiEer-Y ent levels for providing a Water circulation, and a troughlocated in said frame in position to receive the Water dischargedthereinto from one of said pipes, one of the sides of the troughs beingextended and curved at its discharge end to form a battle platedirectingv the discharge of Water from the trough. K

In Witness whereof. I have hereunto set lo my hand at Indianapolis,AIndiana, this 13th day of September, A. D. one thousand nine hundred andteen.
